By analyzing the phase diagrams of some trimethylhalogenosilane/pyridine- and methyl-trichlorosilane/lutidine-systems the existence of the incongruently melting addition compounds Me3SiF · (Pyridine)2, Me3SiCl · (Pyridine)2, MeSiCl3, · (2.5-Lutidine)2, MeSiCl3, · (2.6-Lutidine)2, (MeSiCl3)2 · 3.5-Lutidine, and the congruently melting compounds MeSiCl3 · 2.4-Lutidine, MeSiCl3 · (3.5-Lutidine)2 was proven.
By analyzing the melting point diagrams of some methylhalogenosilane-pyridine systems the existance of the stable addition compounds CH3SiCl3 · 2 py, CH3SiBr3 · 2 py, (CH3)2SiBr2 · py, (CH3)3SiBr · py was proved. In the systems (CH3)2SiCl2/py and (CH3)2SiBr2/py unstable 1:2-complexes are also found. (CH3)3SiCl forms no complexes with pyridine.
